To solve the puzzle, figure out the number I am thinking of (AB). Here are the final coordinates of the cache:
N 41 AB.950 W93 44.209
The number is less than 50. It is not a prime number. It is higher than 30. It is not an odd number. It is divisible by 19. Now you should have it!
This cache is placed as a thank you to Bucknuts because at the Team WHO Blackout event, he gave me an unactivated GeoCoin, and I love it! Please leave the "GeoCoin" for Bucknuts only.
